RE: BME 110 props
I started with an Air Wild NX 27x10 and moved to a Mejlik 28x10. It did a great job, but as the engine got stronger, it got too noisy, so I went to an Air Wild NX 28x10. Great prop, pulled well, quieter than the Mejlik. After a few more gallons, the engine got stronger and the NX28x10 got loud.
I had tried a 28x10 Biela before and the engine didn't like it. Tried it again, and it's now my favorite prop. My 110 turns it about 6500 rpm static, and it's quieter at ALL throttle settings than anything else I've tried. It's wide chord blades "bite" better, and it hovers at a lower throttle setting and rpm, and pulls my 30 pound WH Extra out of the hover with authority and acceleration. Kinda speaking softly and carrying a BIG stick!
